Carrier 24ABA324A0030010 Flame Sensor
A flame sensor is a safety feature that can sense the proper flame during ignition. Because of the safety issues involved, if the sensor produces an error everything stops until the problem is remedied and the system is reset.
Key signs to watch for in a failing furnace flame sensor
- The gas supplying the furnace will not even try to begin an ignition sequence and some type of error flashes on the main board
- The furnace will not even begin to start and spits out an error code on the main board
- The furnace will sometimes work infrequently when it feels like it
